So, I am still without any manuals or info on this Scara. The more I read, the more it seems like Fanuc holds documentation hostage.
But anyway- The onboard pneumatic valves on the SR6ia, is there a regulator as well? Our supply air seems greatly reduced when its run through one of the valves in the robot.
Thanks for any info.
R.U.R., Our next job- and all future jobs if I have my say, will be with ABB. 
I doubt there would be a regulator.
I don't know yet if there is a regulator, but I just got a FANUC SR-3iA today and I'm experiencing something similar.
When I use the vacuum gripper without running it through the robot it holds better then if I run it through the robot so I measured it and while it's not cut in half or anything, it's significant.
I'm hoping that there's just something I don't understand here.
I'm also finding it odd that it has 2 valves, but 4 connection points so if I turn one of the valves on then I get suction on 2 corresponding lines which is annoying as I am only going to use 1 so I have to plug the other.
You shouldn't run vacuum though the lines. It would be much better to supply pressure through the line to power a vac generator mounted on the gripper.
Thank-you, is that just because of the losses? I did it this way thinking that the SR-3 has a low load capacity and I was trying to keep as much off of there as possible.
Also, I got the version with the valves built into the robot, but I'm struggling to figure out how to turn them on/off. I've been reading through documentation trying to find it, but I haven't found it yet.
I'm also surprised to hear that I shouldn't run the vacuum through, it as that is what FANUC was doing when I went to their SCARA training in Michigan.

Those outpots are RO outputs
If you take the cover apart (it's quite simple) you will see the valves at the front closer to the axis 3 shaft
Those valves are not vacuum valves
As far as vacuum (if there were), maybe if you are picking a tiny round piece of plastic lets say 1/4" diameter and 20 thou thick maybe they will work but if you were trying to lift 6 pounds I do no think they will work
The problem normally is the diameter of the hoses. The hoses going through the robot are too small for big air flow, but venturi nozzles need big air flow.

Thank-you!!!
I got 6mm hoses pushed through that should arrive today I'll try it with those instead.
That worked much better, thank-you everyone.
